My invention relates to heat-dissipating devices and it has particular relation to apparatus of the above designated character that shall be adapted for use in connection with electrical or other apparatus normally immersed within a cooling fluid. More specilically, my invention relates to the means of' attaching such heat-dissipating apparatus to the tank or container of the apparatus to l0 be cooled.

The object of my invention is lo provide a connecting device particularly adapted for utilization in mounting detachable radiators of the pressed-metal type on a tank or other contain-er with which they are associated.

Heretofore, it has been customary to mount radiators upon a tank by means of'co-operating coupling members. One of these coupling members is rigidly attached to the tank and the other is welded or otherwise suitably connected to the radiator. The two coupling members are clamped together by means of a plurality of bolts or other suitable connecting means.

One of the disadvantages of this type of connection is that, ordinarily, the entire weight of the radiator must be supported by the welded connection alone, the coupling member offering substantially no reinforcement whatever. Furthermore, it is frequently difficult to weld together a pressed-metal member, which must necessarily be of relatively thin cross-section, and a couplingr member, which must necessarily be of relatively thick cross-section.

According to my invention, an outwardly projecting flange is provided adjacent to the end of the radiator unit. This flange engages a tubular member by means of which the radiator communicates with the interior of the tank and also serves as a support therefor. Means is provided for clamping the outwardly projecting flange member to the tank upon which the radiator is mounted.

In the accompanying drawings, Figure 1 is a plan view of a portion of a tank having a radiator unit mounted thereon by means of a` flange connection constructed in accordance vwith my invention.

Fig. 2 is a crosseseetional view of the strue ture shown in Fig. 1, the section being taken along the line II-II thereof.

Fig. 3 is a cross-sectional view of a radiator of the header type which isf attached to a tank by means of a flange connection constructed in accordance with my invention.

In the drawings, l show a tank wall fl: having a. coupling member o attached thereto by means of rivets 6, or other suitable means. A radiator unit 7', having an inw rdly projecting flange member 8, is welded or otherwise suitably secured to a similarly disposed flange member 10 of an annular member The member 9 is also provided with an outwardly projecting flange member 11 which engages the outer surface of the coupling member 5, thereby establishing communication with the tank 4t. The flange l1 is held in clamping engagement with the coupling member 5 1y means of a collar member 12 disposed between the flange member l1 and the opptr sitely disposed portion of the main body portion of the radiator 7. The collar l2 and the coupling member 5 are provided with lateral projections 13I and ll, respectively, each of which is provided with apertures 15 therein. These apertures are adapted to rcceive bolts 16 by means of which the flange member 11 is held in clamping engagement with the coupling member 5.

In the structure shown in Fig. 3, a header comprising an upper portion 17, is provided with a plurality of apertures in which are disposed a plurality of tubes 18, and a pressed-metal lower portion 19 which constitutes the other side of the header member. The member 19 is provided with a large centrally disposed opening 2O by means of which communication is established with a tank 21, al portion only ot' which is shown. The member 19 is provided with an inwardly projecting flange member 22 surrounding the opening 20. Attached to the flange 22 is an inwardly projecting flange 23 of an annular member 211 some what similar to the member 9 described in connection with Fig. 2. An annular member 25 serves to clamp an outwardly projeetin'g flange member 26 of the member 24: t-o a coupling member 27. The collar member 25 is clamped to the coupling member 27 by means of bolts 28, or other suitable fastening means. The coupling member 2T is rigidly attached to the tank wall 21.

From the foregoing description, it will be apparent that I have provided a radiatorflange connection which eliminates the necessity of welding a relatively thin pressed metal-radiator flange to a relatively thick coupling member and that, in addition thereto, I have provided al structure which is relatively simple and inexpensive to construct and which serves to reinforce the pressed metal walls of the adjacent radiator unit.

I claim as my invention: y

1. In combination, a pressed-metal member having an outwardly projecting portion, a support therefor, and means comprising a collar member and bolts external of said member for clamping said portion of said pressed-metal member to said support. Y

2. In combination, a pressed-metal inember comprising a tubular portion having outwardly projecting flange, a support for said member, and means comprising a collar member surrounding said tubular portion for clamping Said flange to said support.

3. In con'ibination, a radiator provided with a tubular portion having an outwardly-extending annular flange, a support for said radiator comprising an annular member, and means comprising a collar member surrounding said tubular portion for clamping said flange to said support.

4. In combination, a radiator provided with an outwardly-extending annular flange, a support for said radiator comprising an annular member, and means external of said radiator and comprising a collar member engaging the entire periphery of said flange for clamping the same to said support.

5. In combination, a radiator provided with an annular flange, a support for said radiator comprising an annular member, a collar disposed in engagement with said flange, and means external ot said radiator for clamping said collar and said flange to said support.

6. In combination, a radiator provided with an inwardly projecting annular flange, an annular member having an inwardly projecting and an oppositely outwardly projecting flange attached thereto, a support for said radiator comprising` an annular member, a collar disposed in engagement with said outwardly projecting flange, and means engaging said collar for clamping said outwardly projecting flange to said support.

7. In combination, a pressed-metal radia tor provided with an inwardly projecting annular flange, an annular pressed-metal member having an inwardly projecting and an oppositely disposed outwardly projecting iiange, said inwardly projecting flange being welded to the inwardly projecting fiange of the radiator member, a support for said radiator, and means for clamping said outwardly projecting flange to said support.

8. In combination, a pressed-metal radiator provided with an inwardly projecting annular Hangs, an annular pressed-metal member having an inwardly projecting and an oppositely disposed outwardly projecting flange, said inwardly projecting flange being welded to the inwardly projecting flange of the radiator member, a support for said radiator, a collar disposed concentrically with said inwardly projecting flange and in engagement with said outwardly projecting flange, and means engaging said collar member and said support for clamping said outwardly projecting flange therebetween.

In testimony whereof, I have hereunto subscribed my name this 29th day of December, 1920.
